What is pink eye, and how contagious is it really?

In brief:
Viral infection

By far the most common pink eye is a viral infection of the lining of the eye (the conjunctiva) over the sclera (the white of the eye).

It is contagious, irritating, may affect the vision a little and is very socially unacceptable. There are other causes of red eye, some serious. So you should see your ophthalmologist to get a diagnosis and proper treatment.
